i've gave up idea of using mp1e, it seems to be impossible to remove
unneeded things and threads without full rewrite :(
but, Michael Niedermajer today commited some big chanegs to libavcodec, so
it's now 2 times faster! Comparable to mp1e.

Full sized divx4 playback needs avg. 30% of my 1.8g p4 cpu.
It means an celeron 800 should be enough for full rate playback now.
(or p3 600 maybe)

its' fixed too, at least work fine for me.
after seeking it sometimes need few seconds to catch up sync, but then
it's synced again. i can't fix that, as it's in the card's firware.

?
